Fast forwarding to the present, now sees a massive surge of RSS newsreader activity at the top of every hour, presumably because most people configure their newsreaders to wake up at that time to pull their feeds. If I didn’t know how RSS worked, I would think we were being slammed by a bunch of zombies sitting on compromised home PCs. Our hourly RSS surge has all the characteristics of a distributed DoS attack, and although the requests are legitimate and small, the sheer number of requests in that short time period creates some aggravating scaling issues. These issues aren’t enough to make me want to abandon RSS (in fact, I’ll keep pushing it), but its workings can create operational annoyances. If RSS is going to go from fairly big to absolutely huge, we’re all going to need to do a little more work on the plumbing.
